In A While, I Will Be Chasing After A 10gal Because I've Been Wanting To Breed Bettas, Like, My Whole Life.

Breeding bettas takes a whole lot more than just a 10g tank. You really need something like a 20 long for the breeding pair so that they have room to get away from one another. Then, you need something like a 40g breeder for all of the fry. As they grow, you also need a gallon jar with an airstone for each male. You also need live foods for the young fry. Finally, as was pointed out, you need to find homes for all of these fish, which can be difficult.

If you're interested in breeding fish, I would definitely recommend something easier to start with. Of course, livebearers like guppies are very easy to breed, but if you're looking for something with really interesting breeding habits that's still easy to do, I recommend getting a pair of kribensis cichlids.

Yeah, and not to mention that you would probably need to heat the entire room in the 80 degree range. I mean, with all those males in jars it would be pretty impossible to buy heaters that work for one, and are small enough. Plus, that would cost you quite a bit of money. And, on top of all that, you would need to have time to feed, change water, and care for all those bettas in different tanks/containers. It's a lot of work and money, which is why I am not even thinking of it until later when I have the space and resources to make it work.
